Abstract

Temporal flow behaviors in a heated rotating cavity with an axial throughflow and sealed annulus are explored. Generally, for both systems, the ratio of the flow angular velocities to the system boundaries are found, even close to boundaries, not equal to unity. Both systems exhibit similar temporal velocity gradient component distributions. Most unsteadiness corresponds to regions of high tangential velocity gradients. As a result of the flow drift, these spatial gradients are converted to temporal gradients. For the present flows, computations suggest judicious coordinate system angular velocity choices may reduce demands on both convective term treatments and computer resources.
